How to Make Synthetic Gems

Synthetic gemstones are grown in a laboratory instead of being formed by the natural geological processes that create authentic gemstones. Gemstones created in the laboratory are much less expensive for the consumer than natural stones. Much like natural gemstones, synthetic gemstones are created in varying qualities, depending on the technique used to grow the gemstones. Making gemstones using the flux method is a way to produce high-quality gems such as emeralds, rubies, sapphires, and other crystalline stones.

Instructions

1

Combine your desired gemstone component with your solvent solution, also known as flux, in the platinum crucible. Platinum, or any other nonreactive material, can be used for the crucible.

2

Heat your gemstone component and flux mixture in your controlled-atmosphere furnace until it is just above the saturation point, which will depend on the flux and gemstone component you are using. Keep the mixture at this temperature until the gemstone component and flux are combined and form a solution.

3

Allow the solution to cool in the controlled-atmosphere furnace, which allows the crystals to precipitate, or form, and creates your synthetic gemstone. Note that this method of making synthetic gemstones produces gemstones that are only a few centimeters in size while displaying natural facets.
